Yes, I read that post. In my case I want to add a new collection; not adding values to an existing one.
I tried aggregating it to json, and then creating another json and merging the two of them. It didn’t work.
I tried using regex replace to add a new collection after the final one. Didn’t work…
I tried using the merge array function in different ways, to merge the arrays. Didn’t work.
Maybe some of the ways I tried would actually work, but I’m doing it wrong? I dunno. It would be super simple to do this in Python or JS. I’m thinking of sending it as a webhook to a server, fix the array there in Python and sending it back in the response… But that seems like a complicated solution for something that should be very basic…
